it may be readily removed, and the oil beingl conveyed to the peripheryof the wheel? by means depending from the center of the wheel. A furtherobject is to provide a mountind for such oiling wheels which will permitthem to be shifted within the receptacle, especially in a'trough-shapedbody ,adapted to be situated adjacent a row of spindles or reels fromwhich the yarn or thread is being nnwoundi` Other objects are v alsoembodied in other details of construction as will hereinafter more fullyappear.

In the accompanying drawings, Fig. 1 'is a top view/'of my-improvedoiling appliances comprising a single oili'ng wheel.v Fig.`2 is avertical section centrally of Fig. 1, the supply vessel being shown inelevation'. Fig. 3

is a side view of my oiling appliance Showf ing a slightly differentform of receptacle. Fig. 4 is a sectional view transversely ofthe oilingappliance mounted upon a support which is adjustable lengthwise of atrough- Vshaped receptacle. Fig. 5,is aside-view of theoilin'g wheelremoved from the receptacle.

Fig. 6 is a top view of the elongated receptacle showing two of myimproved oiling appliances therein, and also disclosing a supply vesselseated Within one endfof the rec ep-'I ,tacle Fig. 7 yis a cross sectioncorrespond ing to Fig. 4, showingan oiling wheel with' j a funneldepending portion which may be usedto convey the oil upwardly to theabsorbent body ofthe wheel. f Y

j Now referring to Figs. 1 and 2, theelon-- ated receptacle R showntherein is of rela` tively shallow depth and contains `a` cross duponthe seat. Receptacle R may be of any- ,desired length but as lshown inFigs. 1 and 2'4 it-is relatively short andv is adaptedto receive aksingle oiling whe'elWV. Astationary spindle or stem extends upwardlyfrom the bottom ofreceptacleiR and is fixed thereto by a clamping sleeve6 and ya nut 7; Wheel N comprises a hollow shaft 8- adapted to receivespindle 5 and to fit loosely over the upper end of fixed sleeve 6. Theupper end of spindle 5 is preferably rounded or pointed to support thewheel with pin bearing eEect .so that it may revolve very freely. Thebody vof wheel W comprises a number-of iiat .disks 9 of felt or otherabsorbent material clamped between a fiat top plate 10 anda dishedbotiiange beyond the-periphery of the yabsorbent body part 9 to permitsurplus oil which may tom' plate 11. ,The border portion of plate `11 iscurved downwardly and extends as a gather at the periphery of the wheelto drain baclr into the receptacle. In use wheel W rotates'rapidly, andsurplus oil may be thrown outwardly vfrom the periphery there- "of,especially from flange 13, and therefore,

:a circular shield or drum 12 may be affixed l adjustably by bolts orscrews '14 to the vertical wall of receptacle R, the shield or drumextending upwardly any desired distance to encompass flange 13.*r Theupper edge 15 of drum 12 'may be roundedto avoid wear and tear'on the'thread or yarn T, which is caused to pass around the feltbody 9 ofwheel WV under'more or less tension. Brackets 16 affpixed to theopposite sides of receptacle'R support open eye members 17 through whichthe yarn orthre'ad'fT isfcaused to pass when f broughtlin"runningengagement ywith vtlie felt kbody of,the1wheel,1and a smallamount vof oil isftransferred tothe oil orthr'ead dur-ing such runningengagement. To avoid transfer of an excess vamount of oil, prefer to`place some restraint upon the transfer of the oil fromjthe receptacleto the feltbody of the wheel. This maybe accomplished in several waysand in Fig. 2 I show a tubular wick 18 sleevedover hollow shaft `8r andclamped at its upper end in 'facial' contact with the felt body 9 ofthewheel. The lower endof'wick 18 extends into thebodyof oilc'ontainedwithin receptacle R, thereby drawing up a steady supply of oil 'bycapillary* action to thecentra'l part'of the absorbent body ofthe wheel.The wheel is 'rotatedby the running i thread and the oil is carried tothe periphery ,0f the' wheel by centrifugal` force, The

Al/Vhere v'a deeper receptacle It is used, I pre- Y fer toiformsideopenings 2O withinthe wall opposite supply vessel 3 to permit the vessel.to be easily'removed so that the contentsof this vessel may always bevisible, and a glass or transparent vessel is preferred for thispurpose. v Now referring to Figs. 4 to 6 inclusive, I have shownthe'identical wheel disclosed in Fig. 2 except that the centraldepending part of the wheel is shorter. An elongated trough-shapedreceptacle R is also shown in which two or moreV oiling wheels may besupported.- This receptacle may be of any length and a large number ofoiling wheels may be mounted therein so that any number of spindles orwheels mayl be served in a knit-ting, weaving or other machine whereitis common to employ rows of spindles or wheels from which-the yarn orthread is unwound automatically in the operation of the machine. Thedistance between the spindles or wheels may vary on different types ofsuch machines, and in that case it is an easy z matter to adjusttheoiling wheelsfto correspondby shifting the oiling wheels bodily withinthe trough-shaped receptacles. To that end I mount the supporting stem 5for each wheel IV upon a shiftable support 21, which in the presentinstance is shown as a flat bar bent to conform to the inner walls ofthe trough and formed with hook-shaped extremities 22 adapted tooverhang the edges yof the trough to permit setA screw 23 to be used inclamping support 21in any desired position of adjustment lengthwise ofthe trough. I-Iooks or open eyes 17 ymay be mounted upon the lateralextremities 22, and a shield or drum 12 may be adj-ustably afyfixed toand carried by support 21 around .wall- W, thus permitting the wheel andits associated parts 'to be shifted jointly to different positions uponthe trough.

In Fig. 7 'I show an organization of parts which is exactly the same asin Fig. 4, except that wheel W comprises a bottom plate 11 having yafunnel shaped central wall f24 extending downwardly into vthe body ofoil and reduced in diameter at its lower end to perm-itit to engagesupporting stem 5. Per' forations'25 may be formed within the lowerendof the inverted cone or funnel 24 to per V mit oil to pass linto thefunnel chamber.

`'Rapid rotation of the wheel will cause the oil to ascend thedinclinedwall of the funnel and keep felt body 9 sufIicient-ly saturatedwith oil to properly oil the thread passing around the periphery of thewheel.

Vhat I claim, is:

An appliance for oiling a running thread, comprising a receptaclecontaining oil, a vertical stem extendingv upwardly within saidreceptacle, and a wheel engaged by the thread and Inountedto rotate uponsaid stem, said wheel having a central tube sleeved upon said stem intouch with said liquid and adapted to feed-oil to the surface cngagedvby,the thread. l i

5.

11. An appliance for oiling va runningr thread, comprising atrough-shaped recep tacle, a yoke-shaped support-ing member bridgingsaid receptacle having thread guiding devices thereon, a vertical stemaixed to said supporting member, a Wheel supported to rotate upon saidstem having a circumferential oiling surface, and means depending` fromsaid Wheel and connected i therewith adapted to` feed oil upwardlythereto from said receptacle;v

l2. An appliance for oiling a running thread, comprising an elongatedreceptacle, and a thread oiling Wheel mounted to rotate in a horizontalplane and vertically adjustable lto any desired operatingpositiontherein.
